java code LTEgrossaper9:59The classes Name and Date are separateclasses used as properties in the Employeeclass.Class Employee is the superclass of theclasses SalariedEmployeeandHourly Employee. The superclass has theattributes name and date of hire and methodsto set and get these attributes. It also has 2methods: equals() which check if the objectsare same and toString() which convert theproperties to a printable string. Also themethod read() which used as an inputmethod.The SalariedEmployee subclass has inaddition to the attributes of the super-classthe attribute annualSalary and set and getmethods for it. This class also defines theread() method and grossPay() which in thiscase returns the salary of the employee.The HourlyEmployee subclass has in additionto the attributes of the super-class, thehours Worked and hourlyRate attributes. Itprovides 'get' and 'set' methods for theseattributes. Also it provides the methodsequals() and toString(). Finally, it providesan implementation of the methodgrossPay(), which returns the product of thehourly rate with the hours worked for eachemployee.Ims.kku.edu.saAfter creating this class hierarchy create a Mainclass with a main function. This function willhave an array of type Employee and size 2.Place in the position 0 of this array aSalariedEmployee object and in the position 1an Hourly Employee object. Then set someappropriate values for the two objects. Finallycreate a loop that calls the grossPay() method onboth objects of the array and display the.returned value Write a java program as shown in the following UMLclass diagram :( read the details below)Name- first: String- initial : char- last: StringnnualSalary: doubleName(): voidName(String afirst, char aninitial,String alast) voidread() veidgetFirst(): StringgetInitial() : charStringgetLast (): StringsetFirst (String newfirst) voidsetInitial tchar nevinitial): veidvoid setLast (String newlast) : voidtostring(): Stringequala (Nane other): boolean- int month int- int day: int- int year: intDate(): void+ Date(int aMonth, int aDay, int aYear) : voidread():voidget Month(): intgetDay(): intget Year () intset Month(int newMonth): voidsetDay(int newDay) : voidSalariedEmployeeDateset Year (int newYear): voidtoString(): Stringequals(Name other): booleanmlariedispleyee():voidmlariedmployee (Nane,Date airbate, double andalary): vedad): voidouble getAnnualfalary(): doubleid setAnnualSalary(double nevaddtring() Stringquals (Salariedmployee other): booleanrossPay(): doubleEmployeeenplane NanehireDate DateExployee voidExployee ane lane, Date abate voidread():voidgetplane)getiredate(): Datepane ane sevinplane) : veidsetirate (late sevirebate) veidteltring tiequals(Name other) belanHourly Employeehourlytate double-hoursworked doubleHourlyEmployedHourlymployee (ane ampliane,Datate, double anatdouble anders voldread veidgetourlyRate()double get our worked doublewiderstatedouble neuvideturkedidouble newoudtotring() inequals(NourlyEmployee other): booleandouble ressa
